P2287 — Injector Control Pressure Sensor Circuit Intermittent

OBD2 code P2287 flags a problem with the fuel delivery and mixture control (injector control pressure sensor circuit intermittent). Short, gentle driving to a shop is usually possible. Common culprits: weak fuel pump or clogged fuel filter, contaminated or incorrect fuel, faulty fuel pressure regulator.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive with caution. Mixture and fuel-pressure faults can cause stalling, hesitation in traffic and — when severe — catalyst damage. Avoid long trips until diagnosed.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P2287 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the fuel delivery and mixture control for damage, corrosion, chafing or poor contact.
Subsystem check Reproduce the fault: wiggle the harness and tap the injector control pressure sensor while watching the live signal; heat and vibration usually make intermittent faults appear.
Subsystem check Measure fuel pressure at the rail and compare with factory specification at idle and under load.
Subsystem check Check short-term and long-term fuel trims in live data to see which way the mixture is off.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2287 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2287 (parts and labor, USD, independent shop rates): Replace the pressure regulator or sensor: $150–$450; Replace the fuel filter: $80–$200; Replace the fuel pump: $400–$900; Clean or replace injectors: $200–$800. Overall, fixing P2287 usually costs between $80 and $900. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

How do I diagnose P2287 myself?

Start with a scan: confirm P2287, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the injector control pressure sensor, and verify the suspect component against live data before buying parts.

What does OBD2 code P2287 mean?

What are the symptoms of P2287?

Drivers most often notice: loss of power under load, increased fuel consumption, Check Engine Light on, hard starting or long cranking.

What is the most common cause of P2287?

The most common causes are: weak fuel pump or clogged fuel filter, contaminated or incorrect fuel, faulty fuel pressure regulator.

Drive with caution. Mixture and fuel-pressure faults can cause stalling, hesitation in traffic and — when severe — catalyst damage. Avoid long trips until diagnosed.

What does P2287 mean?

When P2287 appears on a scan, it means the control module has flagged a problem in the fuel delivery and mixture control: injector control pressure sensor circuit intermittent. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

“Intermittent” means the fault on the injector control pressure sensor circuit comes and goes — the module sees correct values part of the time. These faults are almost always mechanical: a loose pin, a half-broken wire or a connector that loses contact with vibration or temperature changes.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2287 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

What causes P2287?

wire broken inside intact insulation
loose or backed-out connector pin
contact affected by vibration or heat
weak fuel pump or clogged fuel filter
contaminated or incorrect fuel
faulty fuel pressure regulator
faulty fuel rail pressure sensor or wiring
vacuum or intake leaks skewing the mixture
clogged or leaking fuel injectors

Common symptoms of P2287

loss of power under load
increased fuel consumption
Check Engine Light on
hard starting or long cranking
fuel smell in severe cases
